Descrição: dc.descriptionCorymbia maculata stands out for its resistance to biotic and abiotic stress and for its high-density wood, which is ideal for sawmills, sleepers, posts, firewood and charcoal. In vitro culture techniques can be used for large-scale clonal microplant production, given the difficulty in adventitious rooting via cutting or mini-cutting techniques. The aim of the work was to evaluate the in vitro multiplication, elongation and adventitious rooting stages of Corymbia maculata based on chemical sterilisation of the culture medium, plant growth regulators, gaseous exchange, activated charcoal and growth room lighting. Supplementation of active chlorine in culture medium reduced fungal and bacterial contamination. The best result for the in vitro multiplication stage was observed in the absence of active chlorine and 0.5 mg l−1 benzylaminopurine (BAP). In vitro shoot elongation in culture medium supplemented with 0.5 mg l−1 α-naphthaleneacetic acid (NAA), 0.001% or 0.003% active chlorine, and vessels sealed with a rigid polypropylene lid with one or three membranes was the most suitable. Glass flasks with porous membrane lids allowed gaseous exchange and favoured elongation and adventitious rooting. Microshoots treated with indole-3-butyric acid (IBA) for 48 h (pulse effect) in the absence of light and activated charcoal in the culture medium is recommended for in vitro adventitious rooting of Corymbia maculata.-
